I recently gave a presentation about Behat and automated testing of code at the Denver Drupal Meetup. It's basically the style of testing that we've embraced most strongly at CARD.com.
Here are the slides:
I recently had to validate that input text included only letters, apostrophes and spaces including various accented characters. This was surprisingly tough for me to figure out in PHP.
Some good resources:
Ultimately what worked for me:
Recently our company worked with partners and sponsors to create a thoroughly researched, high quality document about the state of security in the open source Drupal project. You can download the report from DrupalSecurityReport.org, but right now I want to talk about the motivations, the audience, and the funding model behind the report because we feel that we've solved a tricky problem: funding expensive work in an easily copied medium (PDF downloads).
I was just cleaning out my computer and found this little Limerick:
Greg's Unifnished Drupal Limerick
There once was a CMS named Drupal
With code, the developers were frugal
It's only 2megs
Taxonomy means tags
I like to play the bugle
I think I wrote this 2 years ago.
As you can see, the last line is pretty weak. I think the basic flaw is that I ended the first line with Drupal and then had to try to rhyme something close to it which is kind of hard.
